C++. Error while passing pointer by reference.

Hie.

I crossed the very curious sample of code the gcc failed to compile.
Here is the example:

#include <stdio.h>
#include <stdlib.h>

class test {
public:
       int func(int*& a1){
               a2 = a1;
               return 0;
       }
       void print(){ printf("0x%X \n", a2);};
private:
       int* a2;
};

int main(){
       int* a;
       int c;
       test b;
       //
       b.func(&c);
       b.print();
       return 0;
}
ц⌠++ prints the following error

test05.cc: In function 'int main()':
test05.cc:27: error: no matching function for call to 'test::func(int*)'
test05.cc:12: note: candidates are: int test::func(int*&)

I think that it is reasonable not to compile, because, for example, it 
would not possible to guess a correct function to overload. But The C++ 
standard, at first glance, does not prohibit such a coding style.

May be I was wrong in my suggestions, and this is a very useful and 
progressive style.
It would be nice to hear any opinions.

Kirill.
